UnOfficial Asus Rampage II Extreme Thread

How does it handle Linx @ max mem? 5 hours Prime95 is reasonably stable, but it's not uncommon for crashes to occur after that point. Are you working up slowly from a fully tested confirmed stable point?

(1)People often report instability after flashing to a new BIOS; did you set all settings again manually or load the preset saved settings from the old BIOS? (2)Apart from potential settings set incorrectly when loading saved settings from an OC profile, sometimes real voltages can be different despite the same BIOS set voltage being selected. (3)As you are getting instability with the latest BIOS, when all settings are set manually again, have you confirmed all the voltages are what they used to be?

(1)In my case, yes, i have set everything in manual, some of them at their stock voltage, like the IOH, and PCI Express.

(2)About the profiles, you even can't load them anyways... when you try it say something about not matching.

(3)I checked my voltages with a voltimeter and look like it show a little lower compared with what was showing with Bios 1504, so yeah, i tried upping voltages on the critical ones, Vcore Voltage, QPI/DRAM Voltage, CPU PLL Voltage and RAM Voltage, and no go, still i get error at 3 minutes of running LinX. I rolled back to Bios 1504 and passed it.

About qpi volt i know many who use 1.55-1.6 24/7 for stable use of 2000 mhz ram i use 1.55 volt for the 4 ghz uncore no degradation or problems after 6 months.
I used 1.35v for 3.75 ghz uncore.

Anyways you set in BIOs 1.55v you get like 1.48v in full load, at least with my board, measured with a voltimeter.
I had to set 1.525v in QPI/DRAM Voltage to actually give me 1.45v in full load. In idle i get 1.48v.
